Abstract :
An analysis based on distributed body impedance measurements and the use of the Lawrence Livermore National Laboratory Numerical Electromagnetic Code 3 method of moments indicates that the maximum induced current in humans exposed to a typical 10.0-ns risetime EMP is approximately 5 A per 1 kV/m electric field strength. The method allows prediction of induced currents. current densities, specific absorption rate and absorbed energy density for any individual exposed to EMP fields. The validity of the model is verified by comparison with measurements and calculations carried out by K.-L. Gronhang (reports of the Norwegian Defence Research Establishment, 1976 and 1988)
